    Attention to detail is key to keeping any hardworking truck healthy. In our quest to protect the lifeblood of the 2011-2019 Ford 6.7L Powerstroke, we've thought of those details. But before we look at our design, let's recap our last post on the stock oil cooler.

    The stock 6.7L oil cooler is a simple stacked-plate design that uses the engine coolant to warm and cool the oil. The inside of the cooler is separated into two sets of fins. Oil flows through one set of fins while coolant flows through the other. Once the oil temp exceeds the coolant temp, the coolant helps pull excess heat from the oil and releases it through the radiator. This design is adequate for a stock truck, but with more power, or heavy towing, comes more heat.

It needs to stay just the right temperature too. Modern synthetic oils can withstand temperatures up to about 350°F, but as engine temperature climbs, oil begins to thin and lose some of its protective properties.

    For a heavy-duty diesel engine like the 2011-2019 Ford 6.7L Powerstroke, ensuring the oil stays in that sweet spot is essential. Heavy towing or power-adding modifications can quickly drive oil temperatures over the useful range, sucking the life from the 6.7L's internal components. To help combat high oil temperatures, Ford equipped the 6.7L Powerstroke with a liquid-to-liquid oil cooler from the factory.
